I'm trying to communicate with a SIM800L module using the SoftSerial library.
I am trying various pins, but I get no reply whatsoever!

Has anyone got this working?

An excerpt of my code:

serialSIM800.begin(9600);
delay(1000);

if(Serial.available()){
Serial.println("AT\r\n");
serialSIM800.write("AT\r\n");
}
if(serialSIM800.available()){
Serial.write(serialSIM800.read());
}

It works fine when connected straight to my PC over an 3.3v FTDI cable.

Update. It's not the SIM800L. I also can't communicate with an ESP8266 running the "AT firmware".
Does anyone here had any luck having a ESP talk "AT" to another device?
